AI Summary

The release adds the PaddleOCR-VL backend as an alternative to DeepSeek-OCR and introduces lazy loading to improve server startup times. It also expands sampling controls and fixes several issues regarding image requests and model downloads.

Key Highlights

  • New PaddleOCR-VL backend (SigLIP + Ernie 0.9B) support alongside DeepSeek-OCR.
  • Implementation of lazy loading to defer weight mapping until the first request.
  • Comprehensive sampling controls added to both Server and CLI (--do-sample, --temperature, etc.).
  • ModelScope provider improvements for arbitrary repo IDs and exact file paths.
  • Enhanced error handling for requests without images and prompt/image mismatches.

New Features

  • PaddleOCR-VL backend support
  • Lazy loading mechanism
  • Sampling controls (--do-sample, --temperature, --top-p, --top-k, --repetition-penalty, --no-repeat-ngram-size)
  • Model-aware bilingual prompts

Full Release Notes

## New Features

  - `PaddleOCR‑VL` backend (SigLIP + Ernie 0.9B with FlashAttention) is now selectable alongside `DeepSeek‑OCR`. Documentation covers model switching and architecture/memory differences.
  - Model-aware prompts with bilingual Markdown feedback when requests omit <image> placeholders.
  - Lazy loading: the server defers weight mmap until the first request, reducing startup time.
  - Server/CLI sampling controls: `--do-sample`, `--temperature`, `--top-p`, `--top-k`, `--repetition-penalty`, and `--no-repeat-ngram-size` are now recognized across both entry points.

  ## Improvements

  - Common utilities (token sampling, embedding gathers, transformer KV cache) moved into deepseek-ocr-core, trimming duplication between DeepSeek and Paddle crates.
  - Documentation clarifies multi-model selection, DeepSeek-only dynamic crop mode, bilingual terminology, and per-flag behavior.
  - CLI/Server prompt builders choose the correct format per model, improving output quality without manual tweaks.

  ## Bug Fixes

  - ModelScope provider now respects arbitrary repo IDs and exact file paths, fixing Paddle asset downloads that previously fetched the wrong config.json.
  - Requests without images no longer throw transport errors; both sync and streaming responses return a structured bilingual warning instead.
  - Prompt/image mismatches surface as normal assistant replies instead of opaque “prompt formatting failed” errors, keeping clients compatible with standard OpenAI flows.
